HENRY E. REEVE, OF NEW YORK, N. Y.

BINDING-POST.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed April 27, 1908. Serial No. 429,301.

Be it known that I, HENRY E. Rnnvn, a citizen of the United States, residing at New York, in the county of Kings and State of New York have invented certain new and useful Improvements in Binding-Posts, of which the following is a specification.

My invention relates to improvements in binding posts or electrical connectors.

The main object is to rovide a construction which is reliable an to which a wire or electrical conductor, especially stranded wire, may be quickly and securely fastened.

. Another object is to rovide a construction which can be cheap y manufactured.

Another object is to prevent the clamping member from comin off accidentally.

Sim le methods 0 carrying these objects into e ect will be found illustrated in the acoomp anying sheet of drawings and more fully described and claimed hereinafter.

Briefly, the main features, are a threaded or notched flat post secured in a slotted base or support and provided with a perforation for receiving the wire or conductor, in combination with a clamping member and a stop when desired.

Figure 1 is an end view of a structure embodylng my invention. Fig. 2 is a side view showin the base in section. Fig. 3 is an end view 0 the clamping member, Fig. 4 is a side view of the post proper. Fig. 5 is a sectional view of the same. Fig. 6 is a side view of another form of my invention showing the clamp in section. Fig. 7 is a side view of the same taken at right angles to that of Fig. 6

and showing a conductor about to be inof the post is sma sorted. Fig. 8 is a view of a fragment of the base or support with a slot or perforation to receive the post.

The base or sup ort 1, carries the post 2, which is flat and suitably formed as by notches or segmental screw threads so as to accommodate an interiorly' threaded clam ing member on its opposite edges. Int e form shown in Fi s. 2 and 4 the lower end 3 Tor than the threaded portion and is passed through a slot or perforation in the base and upset or riveted as shown in Fig. 2, to hold the post in place.

The post is provided with a perforation 4, just above the support so that a wire or conductor 5 may be passed throu h and be clam ed against the support by t e member 6. nits preferred form the clam ing member 6, iscylindrical, threaded on t e interior to screw on to the post and slotted on the end as at 7 to accommodate a screw driver. Preferably the perforation 4, is bell shaped on one or both sides as shown in Fig. 5, to make the insertion of the conductor easier. The broad surface of the flat post makes it i ossible to employ a large sized perforation.

he relativel narrow edge insures a good seat for the 0 amp 6, without too much friction. The relatively large diameter of the clamp 6, furnishes a powerful gripping area for forcing the conductor 5', against the base or support 1. The fiat post 2 may be conveniently stamped from sheet metal.

To prevent accidental backing ofi and loss of nut while wiring, I may provide a sto as shown in Figs. 1 and 2. The clamp 6, is ere provided with a shoulder or flan e 8. The plate 9, has a tongue 10, formed y cutting an upturned flange or arm of the plate and bending it laterally so as to overstand the shoulder 8. This permits the clamp tobe moved up and down on the post a limited extent sufficient for necessary purposes of adjustment but prevents the clamp from comin off entirely.

n the structure shown in Figs. 6 and 7 no stop is employed and hence no shoulder like 8 of Fig. 2 is necessary. In these figures I have shown a different anchorage. The post 2 has a base 11 larger than the body of the 0st. The support 1 is slotted as at 12 in ig. 8 and the 0st is thrust upward through this slot. he clamp 6, draws the post tightly into position.

The flat portions of the postsin both the forms of Figs. 2 and 6 fittmg snugly m the rectangular slots or perforations such as 12 in the support, effectually prevent the post from turnlng when the clamp is belng adjusted. If desired the lower edge of the clamp may be rounded so as to prevent its cutting the strands of the conductor.

WhatI claim is g 1. An electrical connector comprising a support, a flat post having screw engaging notches onits opposite edges and a transverse perforation for receiving a conductor 'just above the support and a clamping mem- 3. An electrical connector fiat post having screw notches on 1ts op o site edges and a transverse perforation wit a 7 bell mouth and a clamping member operable 5 on the notches of said post.

4. An electrical connector comprising a fiat post having screw engaging notches and a transverse perforation for a conductor and a cylindrical clamping member adjustable on 10 sald post and having slots inthe opposite edges of its outer end.
